If they can make a poly mill it'll be something!
I dont use the Root classification myself other than briefly eyeballing as its a good place to start for many.

BTW how long is a piece of string but whats your experience of the longevity of the milled EVA devices?

They never wear out but if you use a medium density it does crush, Firm, high density lasts for many years I usually advise renewing after 3 - 6 years as a rule of thumb dependent on density mix, type of use and weight of user.. If you use a high density for a light person who only walks short distances ie work, shops, round the pak with the dog, occasional ramble or jog, then they probably would last much longer. Many people come back for second and third pairs simply because they find it tedious to keep changing them into different shoes.

True thing.
That is the trade off with shank dependant devices. Yes you have to make sure the underside of the insole sits neatly on the shank of the shoe but if it does they last wonderfully well.

nuff spec
I have considered a system myself to save orthotic hassles. Always got a bit worried about longevity and bulk. Careful shoe shaping needed?
Dave, are you charging a typical custom orthotic fee for these devices?

Lawrence My fee gives me about £150 profit on each pair. The time for the complete treatment plan is about 3hrs max. IE assessment 1.25hr, design and manufacture 0.5hr, fitting 0.75hr review 0.5hr. The difference in bulk is a small problem but really it is a bit of an illusion because the extra material only fill in the gaps that would be in the spaces around the arch and around the heel cup in a shell type orthosis. Granted you can make a shell orthosis very thin and low profile but then whether or not it actually does anything theraputic is arguable, but at least it fits in the shoe and is comfortable to wear. I fit about 150 pairs a year and rarely have problems with fitting in shoe once I have convinced the lady (its always ladies) to wear a reasonable shoe and that her tiddly little high heeled court shoes that give such bad foot pain are not going to be suitable whatever I put in it, then fitting is OK.

Thnx for that Dave.
You give your pt's a lot of your time for a very reasonable fee. I take your point about bulk, I recently made myself a pair of EVA devices for a pair of my slimmer fitting oxfords and had no real problems as long as they were ground well for fit.

Lawrence Here a recent design that I made on Amfit software. You can see it is very versatile and you can capture 3D weight bearing impressions that may not be possible any other way. Dave

Dave "Indeed you are powerful as the Emperor has foreseen"
When this recession malarky has "blown over" I'll probably give it a go. Or the Orthema version (cadcamorthotics.co.uk). Unless I find a 2nd hand one.
